摘要:
目的:分析多排螺旋 CT(MDCT)增强结合 CT 血管成像(CTA)多维技术术前评估颌面部软组织富血供肿瘤的价 值。方法:选取 86 例口腔颌面部软组织肿瘤患者,以病理检查结果作为“金标准”,所有患者均进行 MDCT 增强结合 CTA 多维技术检查。采用 Κappa 检验分析该技术对肿瘤良恶性的诊断结果与病理检查结果的一致性,比较良恶性肿瘤血供情 况(平扫 CT 值、动脉期 CT 值、静脉期 CT 值、动脉净强化 CT 值、静脉净强化 CT 值);采用 ROC 曲线分析不同脉管 CT 值对 肿瘤性质的诊断价值。结果:86 例口腔颌面部软组织肿瘤患者均经病理检查确诊,其中良性 50 例,恶性 36 例。该技术诊 断口腔颌面部软组织恶性肿瘤 34 例,其中确诊 32 例,误诊 2 例,漏诊 4 例;该技术诊断肿瘤良恶性与病理结果的一致性为 0.878。良性组动脉期 CT 值、静脉期 CT 值、动脉净强化 CT 值、静脉净强化 CT 值均低于恶性组(P<0.05)。ROC 曲线分析 结果显示,动脉期 CT 值(AUC=0.778)、静脉期 CT 值(AUC=0.745)、动脉净强化 CT 值(AUC=0.738)、静脉净强化 CT 值 (AUC=0.781)对肿瘤性质具有良好的鉴别价值(P<0.05)。结论:MDCT 增强结合 CTA 多维技术对术前评估颌面部软组 织富血供肿瘤性质具有良好的指导价值。
Abstract:
Objective To explore the value of the combination of multi-detector row helical CT (MDCT) enhancement and multi-dimensional CT angiography (CTA) in preoperative diagnosis of hypervascular tumors in maxillofacial soft tissues. Methods Eighty-six patients with oral and maxillofacial soft tissue tumors were enrolled and examined with MDCT enhancement combined with multi-dimensional CTA. Κappa test was used to analyze the consistency of the proposed technology with pathological examination as the gold standard for determining benign and malignant tumors. The blood supplies (CT values of plain scan, arterial phase, venous phase, arterial-phase net enhancement and venous-phase net enhancement) of benign and malignant tumors were compared. The diagnostic value of different vascular CT values for tumor properties was evaluated with ROC curves. Results Pathological examination identified 50 benign cases and 36 malignant cases out of 86 patients with oral and maxillofacial soft tissue tumors. Thirty-four cases were diagnosed as malignant tumors when using MDCT enhancement combined with multi-dimensional CTA, and there were 32 confirmed cases, 2 misdiagnosed cases and 4 missed cases. The consistency of the proposed technology with pathological examination for diagnosing benign and malignant tumors was 0.878. Benign group had lower CT values of arterial phase, venous phase, arterial-phase net enhancement and venous-phase net enhancement than malignant group (P<0.05). The results of ROC curves revealed that the CT values of arterial phase, venous phase, arterial-phase net enhancement and venous-phase net enhancement were of high differential diagnostic value in tumor properties (AUC=0.778, 0.745, 0.738 and 0.781, respectively; P<0.05). Conclusion The combination of MDCT enhancement and multi-dimensional CTA provides significant guidance for the diagnosis of hypervascular tumors in maxillofacial soft tissues.
